Power-on Run
The inverter can be set to start operating (output power to the motor) as soon as the inverter
powers up. See caution below. When Ad.10, Power-on Run is set to 1 (yes) and a run command
remains enabled, the inverter will start immediately upon power up. Parameter drv (command
source) must be set to 1 (Fx/Rx-1) or 2 (Fx/Rx-2) along with an active run command. If drv is set to
Keypad, Power On Run does not function.
• Power On Run and Speed Search - A fault may be triggered if the inverter starts
operation while the load is still rotating. With Power On Run enabled, the inverter will
begin its operation in a normal V/F pattern and accelerate the motor. To prevent faults,
set speed search CN-71, bit 4 to 1. The inverter will perform a speed search at the
beginning of the operation.
• With Power On Run not enabled, if the inverter has a run command enabled upon
power up, it will not start. The digital input (Run command) must first be de-activated
and reapplied to begin operation.
Take caution - With Power On Run enabled and a Run command applied, the motor
will begin rotating as soon as the inverter powers up.
